Spring Hello World Application


Hello World Example using Spring, The tutorial given below describes you the way to make a spring web application that displays Hello World message on the Browser.

For that we have created a file called "applicationContext.xml", which defines the bean name, their properties as well as their values.

Required fields:- 

1)class name: A class name is the implementation of the bean class that is described in the bean definition.
2)bean behavioral configuration elements: Here we define the bean behavior that is bean initialization, dependency checking mode, destruction methods etc.
3)constructor arguments and property values :-Defines the no of arguments and the property values that are to be set in the newly created bean.

Note:- We have not defined any of these behavior in our context file since we haven't created any of the bean to be used.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""

dispatcher-servlet. xml:-This is the file from which the mapping from actions to controllers is done .We have used ControllerClassNameHandlerMapping and SimpleUrlHandlerMapping classes to do such mapping. ControllerClassNameHandlerMapping class generate URL path mappings from the class names of the Controller.SimpleUrlHandlerMapping maps URLs to the request handler beans.

p:viewName="index" />:This is the ParameterizableViewController. With the use of this controller we can view the index.
p:suffix=".jsp" />:-This is  InternalResourceViewResolver. With the use of this we can map this name to an actual jsp page.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""
  <bean class=""/>
  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
  <prop key="/index.htm">indexController
  <bean id="viewResolver"
  p:suffix=".jsp" />
  <bean name="indexController"
  p:viewName="index" />

<% response.sendRedirect("index.htm"); %>:-This is a  method of Interface HttpServletResponse that is used to sends a temporary redirect response to the client using the specified redirect location.

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<% response.sendRedirect("index.htm"); %>

index.jsp:-This is the page in which the message is to be displayed.

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
     <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>Hello World-Spring</title>
  <h1>Hello World-Spring</h1>
  <h2>Hello World</h2>
